Laughter triggers the release of endorphins, the body’s natural feel-good chemicals. Endorphins promote an overall sense of well-being and can even temporarily relieve pain.

Laughter protects the heart. Laughter improves the function of blood vessels and increases blood flow, which can help protect you against a heart attack and other cardiovascular problems.

Laughter burns calories. OK, so it’s no replacement for going to the gym, but one study found that laughing for 10 to 15 minutes a day can burn about 40 calories—which could be enough to lose three or four pounds over the course of a year.

Stimulate many organs. Laughter enhances your intake of oxygen-rich air, stimulates your heart, lungs and muscles, and increases the endorphins that are released by your brain.

Improve your mood. Many people experience depression, sometimes due to chronic illnesses. Laughter can help lessen your depression and anxiety and may make you feel happier.

Boosts T-Cells. T-cells are specialized immune system cells just waiting in your body for activation. When you laugh, you activate T-cells that immediately begin to help you fight off sickness. Next time you feel a cold coming on, add chuckling to your illness prevention plan.

Blood flow. Researchers at the University of Maryland studied the effects on blood vessels when people were shown either comedies or dramas. After the screening, the blood vessels of the group who watched the comedy behaved normally — expanding and contracting easily. But the blood vessels in people who watched the drama tended to tense up, restricting blood flow.

Blood sugar levels. One study of 19 people with diabetes looked at the effects of laughter on blood sugar levels. After eating, the group attended a tedious lecture. On the next day, the group ate the same meal and then watched a comedy. After the comedy, the group had lower blood sugar levels than they did after the lecture.

Go ahead, have a good laugh!
